I prefer Blackberry over touch screens. My previous phone was a touch screen and honestly, it was more hassle than it was worth. It was neat to touch the keys and feel a vibration in my finger but the novelty soon wore off. Making a phone call usually left me pressing keys while looking at the phone rather than dialing by memory.
Since I went to my Blackberry, I have had no issues. The Blackberry is also one of the sturdiest phones I have ever owned. I already dropped water on it twice and it fell out of my pocket while jogging (on concrete) and only minor scratches appeared on the corners. The phone is awesome, plus there are a lot of apps available for them.
